ADVERTISING DEVICE.

To all whom it may concern."

Be it known that I, Brennan!) Z. FRIED MAN, a citizen of the United States, residing at Fort lVorth, in the couhty of Tarrant and State of Texas, have invented certain new and useful Improvements in Advertising Devices, of which the followin'gis. a specification.

This invention relates to new and useful improvements in advertising devices, and especially to that class which employs automatic means for consecutively exposing various printed advertisements to view.

An object of the invention is to provide a series of'hinged leaves so mounted that those exposed to view have the appearance of being part of a. book.

Another objectof the invention is to provide automatic means for turning the leaves, one at a time, after an observer has had time to read the printed advertisements on the two leaves exposed.

A further object is to provide means which will conceal the operating mechanism, and mystify the observer.

Finally the object is to provide an automatic advertising device which will be strong, durable, comparatively easy to construct, inexpensive to operate, and one in which the various parts are not likely to get out of working order.

With these and various other objects in view, this invention has relation to certain novel features of the construction and operation, an example of which is described in the following specification, and illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the device, showing the position of the operating mechanism just before engaging a leaf. Fig. 2 is a detail end view of the cylin der in which the leaves are hinged. Fig. 3 a detail side view of the same, showing only one leaf, and that in vertical position.

Fig. 4 is a section of the frame of the leaf. 5 is a side elevation of the cylinder and operating mechanism, the leaves being omitted. Fig. 6 is a sectional elevation taken on'the line AB of Fig. 5. Fig. 7 is a plan detail of the leaf-turning lever and pivoted pawl, and a. leaf shown in position. The lever is shown in section on a line adjacent to the pawl. Fig. 8 is a detail of the slotted pawl employed to turn the cylinder hereinafter to be described.

Serial No. 688,853.

Referring now more particularly to the drawings, wherein like characters of refplaced a casing, said casing being composed of four plates of glass 5, substantially bound together at their corners and edges, and a rear opaque plate 6, having the opening 7 in its lower edge. At the rear of the device a dummy 8 is mounted, and the hand 9 is adapted to protrude through the opening 7 in the plate 6.

The frames of the leaves 10 are constructed of sheet metal pieces having a channel section, as shown in Fig. 4, and each is composed of a base member 11, two side members 12 and a cap member 13, held to the side pieces by the pins 14. The frame thus provided is adapted to receive a printed card, and to allow said card to be removed by providing the removable cap piece 13. T e base member 11 is adapted to receive rod 15, each end of which extends through an aperture 16, said apertures be ing provided in the circular disks l7 and 18, mounted on the shaft 19. The rods 15 are made rigid with the members 11, and are adapted to turn in the apertures 16 in the disks 17 and 18. The apertures 16 are positioned near the outer edges of the disks 17 and 18 in a concentric circle. A bumper coil 20 is attached to each of the side members 12, being placed on one face of the leaf on one member, and on the other face on the other member. The disks 17 and 18 are rigidly fastened to the shaft 19 by means of the pins 21.

The shaft 19, which carries the cylinder composed of the disks 17 and 18 and the rods 15, is rotatably mounted in bearings formed in the lower extremities of the brackets 22 and 23. The bracket 22 is attached tothe top member 2, and the bracket 23 to the top member 3. The bearing formed in the lower end' of the bracket 22 is threaded at one end to receive a threaded pointed screw 24. The point of the screw 24 is adapted to bear against the end of the ment by the jam-nut 25.

The top pieces 2 and 3 are somo'unted on the side walls 1. and the brackets 22 and 23 so secured to sand top pieces, as to give the shaft 19. and consequently the cylinder.

mounted thereon, a slight inclination toward the trout. The object of inclining the cylinder is to' enable an observer to read the advertisements printed on the leaves more readily.

The surface of the bracket 23, adjacent to the disk 18.'is faced and has mounted thereon the following pivoted andslotted members which are employed to rotate the cylinder througha partial revolution, and

' to turn the successive leaves mounted thereon. A bell crank 26, pivoted on a stand 27. is adapted to oscillate through on are of about ninety degrees. The two lugs 28 and 29 are formed on the arin o0 of the bell crank 26, and are adaptedto-rcceive a two pointed pawl 31. Annperture 32 in said pawl 31 is adapted to aline With an aperture in each of thelugs 28 and 29, and a pring cotter 33 is placed through said upertures, thus pivotally mounting the pawl 31 between said lugs. A curved finger or prong 34 is rigidly attached to the portion 35 of the pawl 31. The portionBtl of the pawl 31 is adapted to engage the bottom of a slight recess provided in the arm 30 be tween the lugs 28 and 29, and tlius'preveiit a further rotation of said pawl 31 in a counter clockwise direction, as shownin Fig. 7. A handle 87 is secured to the arm 30 of the bell crank, and is adapted to on.

gage suitable connecting means located-1n the hand 9 of the dummy 8; The pawl 31 and the prong 34 are employed to'grasp and turn the leaves 10, said prong 34 being employed to prevent the pawl grasping more than one leaf ata time. A slotted pawl 38 is slidably mounted on the studs 39 and 0, which studs are screwed into the faceof the bracket 23 ofthe bell crank 26, and is adapted to be operated by contacting with the arm 30. Said pawl is provided with a slot of two different widths. the portion 41 being only of suificient width to slidably engage the stud 39, and the portion 42 be ing of a. somewhat greater width than the diameter of the stud 40. The studs 39 and 40 are placed in the bracket 23 equidistant from the center of the shaft 19. The outer line of the slot 41 and 42 is continuous, and is an arc of a circle having a radius equal to the distance-0f said outer line to the Cfinter of the shaft 19. The portion 41 of the slot is of equal width throughout its length as is also the portion 42, a change in width occurring at the point 43. A tension spring 44 is adapted to attach at one end. to a pin 4."). carried by the powlBS, and at the other cud to n pin 46. carried by the insoles bracket 23. The spring 44- is arranged to slways be under tension and its purpose is to return the pawl 38 to, and hold the some in-thc position shown in Fig. 6, after being displaced in a counter-clockwise direction by the arm 30 of the bellcrank 26. The point 47, of the pawl 38., is 'adoptedto enthe projecting ends 48 of the rods 15, and to impart a counter clockwise rotation to the disk 18, when said pawl38 is operated 1 by the arm 30 ofthe bell crank 26. A baclo ward or clockwise rotetionis prevented by a latch 49, which engages the ends 48 of the rods 15. Saidlutch is pivoted on a stud 5O screwed into the face of the bracket 23. The arm 51 of the bell crank 2d is pivotally attached at its outer end to the upper end of a connecting rod 52. The lower end of the connecting rod 52 is adapted to engage it crank pin 53, said crank pin being; adjust ably mounted-in the slotted crank 54:, which forms one of the spokes in a. drivingsheave 55. The driving sheave 5'5 is rotatably m'duntecl on the lower extremity or a bracket 56, attached to the under side of the frame member%. I

In operation, the sheave 55 is rotated by a motor and a series of reducing sheaves.) or other suitable means, through the use of a cord or belt, all of which are omitted in the accompanying drawings. When the sheave 55 is rotated, it transmits an oscillatory motion to the bell crank 26A, through the use of the crank' 54: end the connecting rod 52. Such oscillatory motion causes the pawl 31, mounted on the arm 30, to engego one/of the leaves 10 shown dotted in Fig.

6. and to turn said leaf. During this oporation. the arm 30 moves the pawl 38 andconsequently the cylinder through such an are that the latch d9 engages the end 48bit the next rod 15. As the 2111130 returns for another leaf, the spring 44 causes the I pawl 38 to follow said armnntilthe end of the portion 42, of the slot in said pawl, is in contact with the stud- 10.,the extrn width of the portion 42, allowing the point 47, of the pawl 38, to lift sutlicient to pass over the end 48 of the next rod15. The pawl is then ready to engage the end 48 of said next rod 15. The operationot the above-described mechanism isthorefore to turn the leaves one at rt time, and to rotate the cylinder in which they are mounted on 7 amount equal to the distance between two it.
